HW?? fi A' approximately-'the reve-rseA- order in whichl I half-ring m for throwing half the needles out of operative connection with the lrnitting cams, and the imparting of oscillating -motion to the ringe, for'throwing certain of the remaining needles, one ata time, into and out of operative connection with the knitting cams, are eifected at the same time by means to be hereinafter described.

It will be understood that the cam cyl-Y inder i and sinker cap y' are rotated and os cillated together. The cam cylinder at its lower part has on its outer face a gear 1.1 engaging the outer gear v13 hf a ring 1.2. The ring 12 carries also an inner gear 14 which engage a pinion 15 on the shaft 16. shaft 16 also, carries a pinion 17 which 5 yengages a gear 18 on the sinlierfhead lo. The

fring 12 is the driving element of the chain fof 'ge'aring described. As shown, the ratio between gears 11 and 13 is one to on a, between pinion land gear 14 one to two,

and between gear 13' and gear 18 one to two,

and the cam cylinder and sinkeilhead therefore have imparted tothem precisely riimilar movements, as if they were rigidly secured y together.

' The ring 12, from which both the c: im cyl- 'inder z' and sinler cap j derive their move- Y vments as above described, is driven from the clutch-shaft 20 by means to be hereinafter described. On the cliitlgh shaft 2O are slidably lmounted the two pinions 21 and 22, which have sleeves to which are yoh :ed the vertically movable arms 24, 24, which are moved up or down in unison as hereinafter -.,described. The clutch is fixed on the shaft 20, between pinions 21 and 22. The ""upper pinion 21 'is constantly'rotated and lower pinion 22 constantly oscillated.

When the arms 24 are moved down,thus` engaging the rotary pinion 21 with the clutch 23 and disengaging the 'oscillatory pinion 22, the ring 12 is continuously ro-A i ftated, thus rotating the cam cylinder z' and sinker cap j. AllVhen the arms 24 are elevated,

thus disengaging the rotary pinion 2l. from thev clutch 234 and engaging the oscillatory pinion 22, the ring '12 `is constantly oscillated,thus oscillating the sink-er capy y'. v

The pinion 21 is constantly rotated by means of` a spur 'gear 25 meshing with the pinion 21. The shaltt26 ot tlie's'pur gear 25 cani cylinder z' and yalso carries 1a bevel gear 2f( driven from a bevel pinion 28 onthe driving shaft t. Y

The pinion-22 constantly oscillated by the following means. 0n the shaft 26 is a crank 29 eonnected by a link 30 with an arm '31 turning on a shatt32. Extending from the hub of the arm l31 is a quadrant 33 engaging the pinion 22.

The ring 12 is of substantially greater thickness than the gears 13 and 14 carried by it. The part of the ring 12 projecting below the gears 13 and 14 rotates in a cup-- shaped casing 35 through which the upper end of the clutch shaft 20 projects. The clutch shaft 20 has secured to it spider 36.

A latch 37 extends from the axis of the shaft 2O through one arm of thev spider 36 into a beveled recess in the inner face of the ring 12. correspondingly beveled and is held inthe recess by means of a spring 38. The inner end of the latch is beveled and engages the beveled upper end of a rod 39 extending axially through the clutch shaft 20. l1t will thus b seen that the drive between the clutch shaft'20 and the ring 12 is not a positive one. So long, however, as there is no obstruction in the knitting mechanism tending to stop the operation of the cam cylinder z' or sinker cap j, these members are driven from the clutch shaft 2O as Vif the ring 12 were positively secured thereto; but in the event of any obstruction to the operation of the cam cylinder t' or sinker cap y', the latch 37 will be forced inward, thusd'estroying the driving connection between the The outer end of the llatch 37 is shat't 20 and the ring 12. ,At the same time the rod 39 will be depressed, and the -machine stopped by means which I shall now describe (see Figs. V1 and S).

On the driving shaft t are the fixed driving pulley 40 and the loose idle pulley 41.

'42 is a belt-shifter secured to the slidable shaft 43. A spring 44 tends to. move the shaft 43 into position to cause the belt shifter 42 to move thev belt into e'ngagernentA with the loose pulley 41. By means of a hand lever 45 engaging a collar 46 on the shaft 43, the shaft 43 and belt-shifter A2 may be moved into position to bring the belt into engagement with the driving pulley 40, the shaft 43 being retained in this position by means of 'i latch 48 (on the collar 46) dropping back ofxa lug 49 on a bellcrank lever 5D. The lowerendlof the rod 39 rests upon one end of an intermediately pivoted lever 51, the otherend of the leverv 51 extending un .ler and between the'ends of, a lever 52. The leve]I 52 is pivoted at one end and its other end is hooked over one end of a'level.` 53, the other end of lever 53 engaging one arm of the bell-crank lever 50. s.

When the-'r od 39 is depressed, as above de- I. scribed, it rocks the lever 5l, and the lever 51 in turn rocks the lever 52, the hooked end of the latter thereby,7 being withdrawn from engagement with the lever 53. lThe latter is thus releaseda and under lthe'inflti'eiioe means of i link 74, with e lever 75 pivoted `means of e pattern retoliet Wheel initially yturningethe sleeve. 67

necessary, as hereinbefore described,to throw out of action the rear bank of needles, which,

as stated, is effected by .moving down the half-ring -m engagingr the tails of the needle levers g correspondingh to said needles, whereby said needles are swung outward and out of operative engagement with the The half-ring-m is secured. to a cross-bar 92 carried by an upright rod 9 Tlierod 93 is carried by one end of a i) l' t).

.lever 94, which is bifurcated between its ends and pivotcd, at its bifurcated'portion, on the machine frame. The other forked end of lever 91 embraces a stud 95, being confined between a head fixed on the top of the stud and a sleeve 97 loose on the stud, said sleeve forming the end of an arm on the lower end of.` the post 60. On the lower end of the stud 95is a head 98, between which and the sleeve 97 is confined a coil spring` 99.

. lll/hen the post (i0 is raised, as it is in shifting' from rotation to oscillation, the sleeve 97 is raised with it, thereby lifting tho forked end of lever 94 and lowering the other end of the lever, thereby pulling down the rod 93, bar 92 and half-ring m and rendering inoperative the rear bank of needles. lVhen the post G0 is lowered, as itis in shifting from oscillation to rotation, the sleeve 97, acting against spring 99, pushes down the stud 95 and the forked end of lever 94, thereby'elevating the half-ring and rendering; the rear bank of needles-again operative. As soon as the machine is shifted from rotation to oscillation and the rear bank of needles is thrown out of action, it becomesv necessary to oscillate the ring r which, as before described, actuated the fashioning rock-plates 0 through the medium of the arms s and the double pawls 79. The oscillation of the ring' r is effected by the following means. On the ring 7 isan arm 100 from which depends a stud 101. on the stud 101 is a sleeve carrying,r a cam Attached lto the sleeve is one end of a lever 101 pivoted between its ends on a horizontal axis. 1The other end of lever 10-t has forks embracing a projection from the upper arm 24 which, as before stated, is

yoked around the sleeved portion of the ro-l tary pinion 21.

The `upper face of the gear wheel 25 is recessed to form an annular cam-way having an outside cam 106 and an inside cam 107. When the arms 24 arc depressed to lower the pinions 21 andY 22 and cause v.the'cam cylinder and sinker cap j to continuously rotate, the cam roller 103 will be vraised so as to lift it ont of the line of travel of the cams 1,06 and 107; but when the arms 24 are faised to raise the pinions 21 and 22 and cause the cam cylinder and sinker cap j Slidable.

to oscillate, the cam roller is 'depressed and moved into line of tr. vel of the cams and 107. Thereafter, during* reciprocation, the cam roller is actuated, first by one cam and then by the other, causing' the ring r ,JQ

knitting of thev heelmnd at the beginning 3g of the knitting fof the toe. During the knit ting of the heel and toe it is desirable toldecrease the tension on the thread sov as' to permit vof the. insertion of an extra reinforcing thread, as hereinbefore described. VVh'en said extra threadvlis introduced and said shift from rotation to reciprocation occurs, certain mechanism, which I will now proceed to describe, operates to lift `the needle cylinder and the sinker head resting thereon; thereby, asis well understood in the art, decreasing the tension on the thread.

Threaded inthe spider o are screws 110 (see Figs. 9 vand 11) carrying'pinions 111 meshingwith an internal rack or gear 112,.. resting on the spider c. axles of the pinions 111 are parts 118 secured to the needle cylinder. By imparting a. rotary` movement to the gear 112,` the screws 110 are rotated, thereby moving the needle. cylinder-vertically. By this means a very fine 'and certain yadjustment of the vvertical position *I the needle cylinder is secured. Further, by lifting gear 112-0nt of engagement with the screws, any one of them can be independently turned a distance of one or more pinion teeth. This is. of special advantage in ease the' needle cylinder should not be absolutely level, as it can beleveled perfectly. by independently adjusting one or more of the screws.A

The gear 112"is turned at'thev proper time automatically by means of the following mechanism (see alsoyFigs. 3 and 11). Secured to the gear 112 is a bracket 114 to which is pivotedi-a rod 115 slidable in a bearing inthe standard 120, on the upper bed'platebJ-Secured to therod 115 are two adjustable pieces 116, 117 carrying respectively screws 118, 119, whose axes are parallel to the axis of the rod 115. The npperend of one arm of a three-armed lever 121 extends back of the screw 118. Another arm of the lever 121 is inline of travel of a cam 122 on the shaft 7 7. As vbefore described the cam shaft'77is given a preliminary turn in order to give a preliminary turn to the ratchet wheel 68 to bring it into opthe time that the; ratchet wheel' cam4 Supported on the i 35 cam wheel 138 and ratchet wheel 137 remain in passing from the toe to the leg-causes the pawl 139 to engage the first tooth'oi' the ratchet Wheel 137 and turn it a distance o tooth. This causes the cani ace of. cam

mf `w eel 138 to ride under one arm ot' a twoarnwu lever 142 pivoted on. the machine frame. rl`he other arm of this lever 142 is thereby caused to engage lthe screw 119. lThis engagement occurs at the same time that the lever 121 is receding from the screw 118, thereby preventing the rod from being returned to its original position and holding the needle cylinder in its raised position. It Will, of course, be understood, that whether the needle cylinder is retained, by

the action of lever 142, at exactly the same level to which it was raised by the lever 121, or whether it is allowed to drop slightly, or whether it is 'raised to a slightly greater height', depends upon the adjustments of the two screws 118 and 119.

During the ratcheting of the next or sixth 'Y tooth .of the ratchet wheel 68 (which occurs i 142 and causes it ,y further, thereby ifting the needle cylinder, thus still further increasing the slackness of the loops. rlhe in this position during the knitting of the garter top. 'w' hen the desired length of garter top has been knitted and it is desired to pass from the garter top to plain singlethread circular knitting, a lug 144 on the pattern chain -engages a cam' 145 on the lever 136, thus again actuating the pawl 139 and causing it to-ratchet the third tooth' oi the ratchet wheel 137. This causes the cam piece 143 to ride from underthelever 142,v

which recedes a certain dist-ance from the screw 119 and permits the spring 123 to draw back the rod 115 and lower the needle cylinder. 1t is not desired, however, to iinmediately lower the needle cylinder to its normal level; that is, to the level which it occupies during the knitting of the ankle andfoot: for the reason that it is desired to continue to knit a certain length of leg below of maximum width. It is the garter top that the therefore desired, notwithstanuinf1r reinforcing thread is clamped and cut as .loops 'of .the yarm 'riphery 'of the cai'n wheel 138 is so formed soon as the garter top 1s completed, to maintain a certain degree of slackness in the Consequently, the pethat the part beyond the cam piece 143 is still high relatively to the low part of the periphery, and therefore the needle cylinder,

as above described, is not lowered to its lowest level. lt may be mentioned here that, when the ratchet wheel 137 and cam wheel 138 are given their final turn by the pavvl 139, one of the lugs 146 on the cam wheel 70 138 engages one arm of a two armed lever 147, causing the other arm of this lever .to move from under a projection 148 of' the rod 149, allowing the latter to move down. The

moving down of rod 149 permits the thread 75 to be clamped and cut.

The ratchet wheel 137 and cam wheel 138 remain stationary during the knitting of that part of the legbelow the. garter top and, above vthe ankle,

the fabric; that is, to gradually decrease its diameter. This 's effected by gradually increasing the tension on the yarn, which in turn is effected by gradually lowering'- the 8;-1

its lowest level. At the desired to so gradually another of the needle cylinder to point where it is lower the needle cylinder,

pins4 140 projecting Kfrom the pattern chain engages another of the lugs 141 on th 9g ratchet wheel 137 and turns the ratchet. wheel 137 and cam wheel 138 a part of a revolution-say, something less than half a revolution. This causes the'lever. 142. to pass along that part the 'wheel 133 beyond the cam piece 143, which, it will be noticed, is a gradual ineline descending to the low part of the pe riphery. During this operation, the lever 142 gradually recedes from the screw 119, 100

and the spring 123 draws back the rod vv115 until the gear 112 and screws 110 are turned .to lower the needle cylinder to its lowest level. The machine now' proceeds to knit or lower portion of the leg. At .10.1

the ankle, this point it mayjbe stated that after the second high point'of the cam 132 engages the lever -134 and Vdictates the elevation of the needle cylinder to its maximum height, the 'pawl 70 returns to the position where the pawl plays idly. on the long tooth 80, which continues until a lug on the pattern chain again actuates the lever 73 and thereby gives the'rat'chet wheel 68 its initial turn preparatory lto again 115 shifting from rotation to oscillation, which, as before described, occurs when the knitting of the ankle is completed and it is dew sired to knit the heel.

From the foregoing understood that the variousoperations here- Y inbefore described are all controlled by the turning of ratchet Wheels 68 and 137 and it may be well, therefore. to briefly review the relative positions of these Wheels during 125 the entire cycle of' operations. Y

Assume that the ankle, or lower portion of the leg, is being knit. 'During this operation, bot-h ratchets 68 and -137 are-Station? A ary, the vpawl 70 is playing idly on the long 18o,
